The speeded up renovation of old buildings in the city centres is related with the estimation of the state of their foundations. The renovated buildings are often redone for another goal of exploitation, and this is the reason why the load onto the foundations changes. Such foundations require underpinning. As usual, towns have been established nearby the rivers, and therefore the base of a number of old town buildings are of various alluvial deposits, above which the cultural stratum is being found. In many cases the foundations must be reinforced namely in this stratum. Jacked piles are a very convenient and effective way of underpinning the foundations. We can choose the required pushing force and the length of a pile in accordance with the projected load for a pile. The pushing force is one of the most important criteria to define the bearing resistance of a pile. The choosing of the pushing force, the finding the length and the bearing resistance of the pile installed in the sandy ground is introduced in this publication.
